4.0 Understanding your A2B 

4.1 A2B Overview

Having read this section, if you are still unsure, please ask an A2B 
dealer to explain any functions or features that you do not understand 
before your first ride.

The A2B has a ’true pedal assist’ function, this means the motor 
engages only when the rider is pedalling. So you can choose to 
ride with the pedal assist switched off and go places under your 
own steam, yet have the comfort of knowing you can switch the 
motor on for an extra boost at any point during your journey.

4.2 Starting and stopping 

1.  Select a quiet area away from cars, other cyclists, obstacles or 

other hazards.

2.  Make sure that the battery is fully recharged.
3.  Power ON the electronic system by turning the battery power on.
4.  Raise the kickstand into the riding position. DO NOT sit on the 

A2B while it is supported by the kickstand, you will damage the 
kickstand and possibly the frame.

5.  Mount your A2B and get comfortable.
6.  Apply motor power by pedalling the A2B .
7.  Test the brakes at slow speed. The right brake lever actuates the 

rear brake and the left brake lever actuates the front brake.  
Applying brakes too hard can lock up a wheel, which could 
cause you to lose control and fall.

8.  Check out the handling and response of your A2B. Familiarise 

yourself with how the suspension responds to application of the 
brakes and shifts in rider weight. 

 Remember that there are power cut-off switches embedded 

into the brake levers. When you apply the brakes, power to the 
motor will turn OFF. Therefore, do not hold the brake levers when 
you want the motor to run. 

push it into the closed position. The efforts are appropriate 
if the lever leaves a mark on the palm of your hand when 
pressing. A properly closed quick-release cannot be moved 
anymore unless it is reopened as specified above. If you 
can move the mechanism slightly, open the lever of the 
quick release, turn the adjusting nut by another 180° and 
try again. 

4.  After height adjustment, check if the saddle cannot be 

moved in any direction. 

  An improperly attached saddle may lead to severe or even 

fatal injuries. Ensure that the saddle clamp screw (saddle 
post - saddle) has been tightened using 27 Nm.
